420Girl's First Grow - Northern Lights - 2017


New Member
Hello kind folk :ciao:

I thought I'd start a journal for anyone who's interested and also it might be better than posting a million different questions in other parts of the forum!

About me: After numerous health issues for over a decade and regular meds not helping, I've decided to medicate in a different way! I've actually never smoked pot before so this should be interesting :laugh2:

Essential info:

Strain: 1x Northern Lights photo & 2x Northern Lights auto
Age: 4 months & 3 weeks
Grow room: Secret Jardin DP90 (90x60x90cm)
Lighting: 2x 15w CFLs, eventually will be 4-way 2ft T5s (96w)
Light cycle: 16/8
Medium: Coco coir
Nutes: Very diluted chilli nutrients
PH: 6
Temps: Between about 74-81
RH: No idea!
Ventilation: 6" desk fan and tent vents (in the process of deciding on a 4" inline extractor fan for when I reintroduce the T5s)

Last October I naively thought I could grow an NL feminized photo on my windowsill during winter, but soon realised this was not to be the case! The first seedling died (RIP) and the second stretched like crazy but is still alive after spending several months on my windowsill (growing INCREDIBLY slowly!) and is now enjoying her new home in my tent I bought about a month ago, along with T5s and a desk fan. I actually had problems right from the start, however. I germinated 2 NL autos and put them in the tent with the other seedling, but I didn't realise how much heat would be generated from the T5s so unfortunately my tiny seedlings suffered from major heat stress as I didn't have an extractor fan. I removed the T5s and replaced them last week with 2 15w CFLs which they're enjoying a lot more. Heat generated from them is next to nothing so temps in the tent are manageable at the moment. My ladies' first set of true leaves shrivelled up and died under the T5s (which you can see in the pics) but the new ones coming through look nice and healthy (although surprisingly rounded!). The photo is actually doing pretty well (compared to previously!) under the new lights too and boasts the biggest leaves. They're still growing pretty slowly though but I guess it's because they're only getting 30w of light at the moment.

These were my autos under the T5s a couple weeks ago:

And today (excuse the yellowness of the 2700k CFLs):

This is my 4 month old photoperiod. You can clearly see the bad state of the lower leaves:

Unbelievably the lower setting on my fan (which I need) broke pretty much straight away and last week, just as I was about to swap out my T5s for CFLs, the damn lamp lead broke too!! So I removed 3 of the 4 bulbs from my T5 unit and put that back, but it then started buzzing (which it never did before) which freaked me out so I got a replacement lamp lead and attached the CFLs. So unfortunately so far my grow has been nothing but stress and worry! Hopefully though once I get everything in place it might settle down and become more enjoyable. Also I haven't slept well because the only place I can keep my tent is in my bedroom so the noise from the fan keeps me awake at night, and I haven't even got the extractor fan yet. I nearly gave up last week when the lead broke because it just seemed like something was telling me not to do this :surrender:

I've made a ton of mistakes so far so if I even get ANYTHING decent from this grow I'll be really happy. It's been a massive challenge already so I'm hoping all my hard work will pay off.

:thanks: :Namaste:

Looking good bro. Don't worry about the lower leaves on the little fella will perk back up. Remember it's only your first grow and we are here to help.

Sorry to thread jack but heres some motivation. This guy was neglected and left with no nutrients for 4 weeks you can see the yellowing of entire plant. Not looking good.

This is the same guy after a lot of attention and been fed properly with Advanced Nutrients Micro, Grow, Bloom at 4ml per feed

These plants will recover from many bad situations.

Whoa! Look at that - it's like an explosion of green, leafy goodness. Thanks for the support and sub!

Unfortunately my bulbs came when I was out today so my girls are going to have to wait another day before they get their lumens doubled. My photo (biggest plant in the pics) is actually smelling already by the way! It's so small and I figured they only start smelling when they flower but perhaps I'm wrong! It was amazing when I opened the tent the other day and thought..."Hmm....I can smell weed!" :laugh2:

So I've got my new bulbs installed and guess what...my carbon filter that was supposed to come today wasn't delivered!! Oh well it's a good job I'm not in a hurry to receive it. Not sure of the quality of the bulbs either, they're definitely brighter than my last ones but not double the brightness I don't think, despite being double the wattage. Anyway, here are some updated pics:

It's not that easy to tell from the pics because of the light but the cotyledons on the bigger seedling have started to turn yellow. I figure nitrogen def so I've given it some more nutes and if it doesn't get better I'll mix up some more and increase the strength a bit.

Environment is KING. You need to control the weather inside the tent (temps & rh) You want to shoot for 77-81 & 55-60% rh for lights on.
68-70 & 50% rh for lights off.

Thanks for the info Budley & Pennywise! My temps are always within that range which is good, not sure about RH but it's definitely more inside the tent than outside. I've put a tub of water in the tent for evaporation and also put some of my chilli plants in there which hopefully will help increase humidity.

Plants are looking healthy, still growing pretty slowly though. They're 29 days old and still little seedlings! I'm gonna reintroduce my T5s now that I've got an extractor fan I think.

Thanks Kushman! Sometimes when pennywise isn't here I feel like I'm talking to myself haha :laugh2: And yeah sounds good, it's so much better to share this experience with people so we can all learn :Namaste:

Thanks again for the tips pennywise, they did seem to perk up when I gave them more water and nutes and I'm still not watering as much as I could I don't think, so gonna go and give 'em a drink now :)

Hello, found your grow journal. Plant is looking very healthy! I'll be subbing so I can see how you get on :)

Think I'm going to go coco for my next grow. LEDRF is correct, it's pretty much impossible to over water in coco. Definitely try and water her every day if you can, some people even recommend watering twice a day in coco so don't worry about over feeding :)

Thanks Blue! I (like a lot of people probably) was quite worried about overwatering so was very hesitant about it but now I'm watering with confidence thanks to you guys!! I can already see my girls are definitely doing better since giving them more water and thus more nutes, I just checked on them and they're bigger already :) I can't wait for them to get big enough so I can start doing some LST.

Subbed to your grow too :thumb:
